[tex](2x - 5)(x + 3) \\ 2x(x + 3) - 5(x + 3) \\ 2 {x}^{2} + 6x - 5x - 15 \\ 2 {x}^{2} + x - 15[/tex]
(a+b)(c+d) = ac+ad+bc+bd(2x-5)(x+3) = 2x(x)+2x(3)+(-5x)+(-5(3))(2x-5)(x+3) = 2x²+6x+(-5x)+(-15)(2x-5)(x+3) = 2x²+x-15 (pilih yg C.)[xcvi]

(2x-5)(x+3) = 2x(x)+2x(3)+(-5x)+(-5(3))
(2x-5)(x+3) = 2x²+6x+(-5x)+(-15)
(2x-5)(x+3) = 2x²+x-15 (pilih yg C.)
